title: [The polymorphism of the C line pf palmar dermatoglyphics and its use in population and human pathology studies].
abstract: The present work contents a study of the C line polymorphism, from the dermatoglyphic picture of the palm and its variability regarding the population of four rural communities from the Suceava department and from two groups of mentally handicapped and deaf and dumb children coming from special schools of Moldavia (700 normal and 487 handicapped subjects). Generally speaking, the studied series present a behavior similar to that of the Romanian and European population, although, in both cases, there are some distortions or important dermatology-phases consisting in a rise of frequency for the forms of partial and total suppression of the C line to values (Cx = 25.75% at Panaci and Co = 10.25% at Vama) which surpass even those reported for the 21 trisomy (Cx = 25%, Co = 7%) and some important inversions from the classical dimorphic line regarding the distribution of the two modal types CR and CU, materialized in an alignment of the palmar ridges more transversal for men instead of women (CR : men > women instead of women > men) and conversely for the intermediary to oblique alignment (CU : women > men instead of men > women).
